RSH(1C)RSH(1C)NAMErsh - remote shell
SYNOPSISrsh host [ -l username ] [ -n ] command
host [ -l username ] [ -n ] command
DESCRIPTION
Rsh connects to the specified host, and executes the specified command.
Rsh copies its standard input to the remote command, the standard
output of the remote command to its standard output, and the standard
error of the remote command to its standard error. Interrupt, quit and
terminate signals are propagated to the remote command; rsh normally
terminates when the remote command does.
The remote username used is the same as your local username, unless you
specify a different remote name with the -l option. This remote name
must be equivalent (in the sense of rlogin(1C)) to the originating
account; no provision is made for specifying a password with a command.
If you omit command, then instead of executing a single command, you
will be logged in on the remote host using rlogin(1C).
Shell metacharacters which are not quoted are interpreted on local
machine, while quoted metacharacters are interpreted on the remote
machine. Thus the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the localfile localfile, while
rsh otherhost cat remotefile ">>" otherremotefile
appends remotefile to otherremotefile.
Host names are given in netinfo(5) if NetInfo is running or in the file
/etc/hosts if NetInfo is not running. Each host has one standard name
(the first name given in the file), which is rather long and
unambiguous, and optionally one or more nicknames. The host names for
local machines are also commands in the directory /usr/hosts; if you
put this directory in your search path then the rsh can be omitted.

SEE ALSOrlogin(1C)netinfo(5)BUGS
If you are using csh(1) and put a rsh(1C) in the background without
redirecting its input away from the terminal, it will block even if no
reads are posted by the remote command. If no input is desired you
should redirect the input of rsh to /dev/null using the -n option.
You cannot run an interactive command (like rogue(6) or vi(1)); use
rlogin(1C).
Stop signals stop the local rsh process only; this is arguably wrong,
but currently hard to fix for reasons too complicated to explain here.
